Does the HOBO® MX2304 have the ability to log water temperatures with the external probe? If not, do you have a device that does measure water temp with the same functionality (bluetooth, exportable data, etc)? Thank you!

The sensor tip of the MX2304 is rated to be submerged in water of up to 50°c for up to one year.  While rated for measuring water temperature if you are planning to use it for a long term deployment we would recommend looking at the MX2201 which is designed to be submerged. It can also be read wirelessly via Bluetooth but it won’t transmit while submerged so you would have to raise it above the surface before you connect to it.
